I am writing a journal file to take images at a large no of iso-surface planes. The planes are named as "X_0.5", "X_0.6", and so on. I want to automate the process by writing a journal file i.e. write a loop (do or for) and in each loop I want to specify the name of the iso-surface at which image has to be taken. But the main problem is I do not know how to pass on the name of the iso-surface as a string to the fluent text-command. Any ideas how to do that in a loop in scheme program?
Algo would be like:

do (start at i=0, increment by 0.1, till 1)
S= "concatenation of ("x_0." and "i") ;;; How to do it in fluent
/display/set/contours/surfaces
"S" ;;; How to do it in fluent
/display/hard-copy
"S".jpg ;;; How to do it in fluent
end
Thanks in advance.

The above scheme will create iso-surfaces from z=0 to z=1 at an interval of 0.1. and the name of the planes will be z-plane-0.1, z plane-0.2,....and so on. you can modify the start, end and interval of the iso surfaces in the first line of the scheme.
Also, you can change the name of the plane in the 3rd line. And if you want the iso surface of x or y plane instead of z, you can do so by changing z-coordinate to x-coordinate or y-coordinate respectively. Remember x used in the above scheme is just a variable and not x plane.

This is an example of saving velocity contours at z plane 0, 0.1, 0.2,.....0.9 & 1 where min and max maginutde of velocity is 0 and 60 m/s.

Dear vaibhav

Would you give us further elaboration on the format in this statement:"surface/iso-surface z-coordinate z-plane-~a () () ~a" x x))
I need to understand what ~a, (), (), and ~a stand for? Why you have specified two of "~a" and "x"??
Thank you.

Thank you.

I examined it manually in Fluent!

"~a" stands for random variable, like % in C language.
"()" means that we simply press "enter" and do not specify any names.
"x" at the end of line is the same loop variable and two of "x" correspond to two of "~a".

Hi
I want create lines which are intersection of some iso-surfaces(eg. what you created before) and wall boundary condition. is that possible with scheme you mentioned?
is there any scheme?
thanks
